To (Add whom it may concern:

Be it known that l, Vroron Ynunnre, c1t1- zen o f the Argentine Republic, resldmp; at

No. 332 Chacabuco Street, Buenos Aires,

Argentina, have, invented certain new and useful improvements in Apparatus, for Admitting Additional Heated Air into Internal- Combustion Engines, of which the following' is a specification.

My invention relates to a novel apparatus for heating and admitting air, and has for its object to provide for a very simple apparatus which may be applied to the air and gas inlet pipes of carbureters of internal combustion engines, particularly to those of the so-called Ford type.

Eiaid apparatus, when connected to the inlet pipe of such motors, admits a flow of hot air which fosters the combustion of the gases, thereby regulating the working of the englue and allowing a considerable economy in the incl. 7

In order that my present invention may be clearly understood and easily carried into practice I have illustrated it in the accompanyinp; sheets of drawings, which show a preferred embodiment of the said invention, such as may be applied to a Ford type of engine.

In the said drawings,

Figured is a perspective view showing the apparatus full size.

Figure 2 is a front view of the air and gas inlet pipe connected with the carbureter in the Ford engine.

Figure 3 shows the rear side of the said inlet tube.

Figure 4 is a transverse section of the ap paratus.

Figure 5 is a vertical section on line ofFigure 1.

Figure 6 is a longitudinal sectional view of the tube by means of which the apparatus is connected to the inlet tube.

Figure 7 shows the intermediate plate.

Similar characters of reference denote like parts throughout the said drawings.

The apparatus consists oi a cylindrical iron or lilre receptacle having at the upper end a flange on which the cover maybe seated. Said cover is firmly held in posi tion by means of a screw T, a nut J and a cross-pin K, whereby an air-tight joint is formed. To this end it has been found advisable to surround the said upper flange with asbestos fibre or the like.

l l ithin the receptacle and resting on its bottom there is a quantity of the finest copper wire, its object being to take up heat and to provide for an extensive heat-radiating surface when the atmospheric air enters nut engaging the upper face of head L and being locked in position by a cross-pin a. The lower end of spring); R hears upon the adjacent end o'f the part A, which is reduced, as shown at G to provide a seating for the valve.

As may be seen from Figure 5 the two openings 0 and O in the said reduced end G- allow the entrance of atmospheric air.

As the suction of the air is produced by the working of the engine, the said valve H seats and unseats rapidly, therebvregu lating; the admission of atmospheric air within the apparatus.

The air, on entering the receptacle through the openings 0, O and the extension A, is forced to make a long; course in close contact with the copper wire, to which end a downwardly-convexed baiile or deflecting plate NN (Fig, 4) is provided, The said wire is rapidly heated by the working of the engine and maintains a uniform temperature.

The heated air is withdrawn from the receptacle by the suction of the engine through the outlet E and the intermediate connecting: tube E--F, the end E of the latter beinc; threaded in the said outlet E, and enters the inlet pipe at F, at which point the end F of the tube is attached to the inlet pipe. The hot air thus supplied to the inlet pipe is added to the explosive mixture which enters the end C of the pipe from the carbureter, the result being an appreciable saving of naphtha.

The apparatus is held in position by means of a steel plate P.

It is obvious that many constructive and other changes may be introduced without deartin from the aresent invention the see )e P h l of which is clearly set forth in the appended claiming clauses.

Having now fully described and ascertained the nature of my present invention and in what manner the same is to he car ried into practice I declare that what I claim is:

An apparatus for supplying auxiliary heated air to internal combustion engines, comprising a metal receptacle adapted to he secured sufiiciently close to the engine to he heated thereby; an upstanding valve easing on the top Wall of the receptacle opening thereinto at its lower end and provided adjacent its upper end with an air inlet; a

spring-controlled valve in said casing normally closing said inlet to prevent admission of air into the receptacle; an upstanding outlet member also on the top wall of the receptacle and opening therelhrough; a connecting tube having one end engaged in said outlet memher and the other end opening into the inlet pipe of the engine, whereby the engine suction exerted through said inlet pipe will open said valve and cause a current oi atmospheric air to he drawn through said inlet successively into and through the valve casingn the receptacle and outlet memhen the ronneeting tuhe and the inlet pipe and into the engii'le; and a mar-s of line heat-conducting material disposed within the receptacle in the path of the air current and adapted to he heated hy its contaet with the walls of the receptacle and to heat said air current during the passage of the latter through the receptacle.

In testimony whereof l aliix my signatuir.
